| contents | In this paper we propose a novel design approach for an ultrathin metasurface energy harvester based on a surrogate model of dipole antenna. A significant advantage of this idea is the reduction of the time of the design process retrieved from a surrogate model of the resonant half-wave dipole antenna embedded in a medium. However, the design of a new electromagnetic energy harvester with a deep-subwavelength thickness (~ 0.004λ) is the major concern of this work. The proposed structure shows an enhanced level of absorption. Decreasing the thickness of metasurface as a new classification of energy harvester, we have managed to demonstrate the stability of the efficiency. In addition, this metasurface energy harvester proved to maintain a relatively constant performance (efficiency and HPBW more than 85% and 7%, respectively) as the angle of the EM incident wave was changed over a range of 75 degrees in the transverse magnetic (TM) polarization. |
